Spent fuel storage pool

Abstract

The invention provides a spent fuel storage pool which comprises a plurality of pool structures, wherein the pool structures can be communicated with a sea area and can place spent fuels. Each pool structure comprises a cooling water cold pool, a cooling water hot pool and a pool, wherein the cooling water cold pool and the cooling water hot pool can be communicated with the sea area, the pool canstore a plurality of spent fuels, the cooling water cold pool is communicated with the pool, the cooling water hot pool is communicated with the pool, and a control chamber is arranged inside the cooling water cold pool and communicated with the outside through an escape channel. As a current spent fuel pool is usually built inside a nuclear power station, the volume of the current spent fuel pool is very small, the current spent fuel pool is easily saturated, a cooling system is complicated and high in cost, and safety guarantee measures are difficult.

Description

technical field [0001] The invention belongs to the application field of nuclear technology, in particular to a spent fuel storage pool. Background technique [0002] When nuclear fuel is used in a reactor, due to the consumption of fissile nuclides, the generation of fission products and heavy nuclides, the fuel reactivity changes, and finally the reactor can no longer maintain criticality, so the nuclear fuel must be replaced to a certain extent. Fuel that has been irradiated and removed from the reactor is also known as spent fuel or irradiated fuel. Spent fuel has a certain level of radioactivity and still generates residual heat, requiring extra care in its storage and handling. Since water is a natural neutron blocker, and circulating water can also take out excess heat. Therefore, using water pools to store spent fuel is a common method. The current spent fuel pool design is usually built inside the nuclear power plant, so the volume is very small and it is easy to...
